Cannon posted an open letter to his "sister" Wednesday, explaining how her behavior makes some sense to him, and how easy it is for young stars to fall into the traps that have ensnared his "All That" costar.
"Lately I have been hit with an onslaught of questions about someone I consider family, someone I watched grow up, and someone I genuinely feel is one of the most pleasant human beings I have had the pleasure of meeting, Amanda Bynes," Cannon wrote on his website.
"The entertainment industry just consumes people and spits them out like flavorless bubblegum," he wrote. "A few chews of enjoyment then they’re under a city bus bench...
"When a person is told all of their life that they are awesome, the best, the greatest and they are catered to every moment of the day. Imagine being the breadwinner in your household before you can even drive. Imagine you parents, teachers, and employers NEVER telling you NO...
"Anything you ask for or want, the world gives you, at some point you are bound to self-destruct. I call this 'access to excess'. I’ve seen it happen to many of my friends and colleagues young and old. It goes back to that old saying; 'Too much of anything is bad for anyone'. Whether it’s fame, money, sex, drugs, attention. It’s all a dangerous addiction. When there is no balance in your life a person will always become victim to their reality or lack thereof."
Cannon finished his letter with a direct appeal to Bynes.
"So I say to my sister Amanda Bynes you’re not alone," he wrote. "I’m here for you. I understand. I care and I appreciate you, because that’s what family does and that’s what family is for. I also extend this to anyone else in my life, past or present that may find themselves in hard times. I’m here! Call me! Because I truly believe, the hand you’re helping up today may be the one you’re reaching for tomorrow.
Bynes is undergoing mental evaluation after she was hospitalized on an involuntary psychiatric hold.
